Title (EN) PROCESS FOR PREVENTING THE FORMATION OF DEPOSITS IN THE HEAT EXCHANGER SYSTEMS
(FR) PROCEDE EVITANT LA FORMATION DE DEPOTS DANS LES CIRCUITS D"ECHANGEURS DE CHALEUR
Abstract: front page image
(EN)Process allowing to prevent the formation of deposits onto the walls of heat exchangers in cooling or heating systems into which an aqueous heat-carrier liquid circulates. This process consists in mixing with the heat-carrier liquids, 0.3 - 5% approximately by weight of a product obtained from a poly-addition of ethylene oxide and propylene oxide on a mono-alcohol, water, a diol, a triol, the ethylene oxide representing 60 - 90% by weight of the fixed alkylene oxides. This process can be applied particularly to the cooling systems of internal combustion engines.
(FR)Procede permettant d"eviter la formation de depots sur les parois des circuits de refroidissement ou de chauffage d"echangeurs de chaleur dans lesquels circule un liquide caloporteur aqueux. Ce procede consiste a melanger aux liquides caloporteurs environ 0,3 a environ 5% en poids d"un produit de polyaddition d"oxyde d"ethylene et d"oxyde de propylene sur un mono-alcool, l"eau, un diol ou un triol, l"oxyde d"ethylene representant de 60% a 90% en poids des oxydes d"alcoylene fixes. Ce procede peut en particulier etre mis en oeuvre dans les circuits de refroidissement de moteurs a combustion interne.
